China Bird Flu: Two Men Die in Shanghai
Two men have died in the Chinese city of Shanghai, after contracting a strain of bird flu not previously known in humans, Chinese officials say.
The men, aged 27 and 87, both fell ill with the H7N9 strain in February and died some weeks later in March, Xinhua news agency reported.
A woman of 35 who caught the virus elsewhere is said to be critically ill.
It is unclear how the strain spread, but the three did not infect each other or any close contacts, officials say.
While both men who died were in Shanghai, the third victim was reported in Chuzhou in the eastern province of Anhui.
According to China’s National Health and Family Planning Commission, all three became ill with coughs and fevers before developing pneumonia.
Commission experts said on Saturday the cause had been identified as H7N9, a strain of avian flu not thought to have been transmitted to humans before.
There is no vaccine against the strain, the commission said, adding it was currently testing to assess its ability to infect humans.
